RAl LWAY-CAR.

SPECIFICATION forming part of Letters Patent No. 459,896, datedSeptember 22, 1891.

Application filed November 28, 1890. Serial No. 372,966. (No model.)

To all whom it may concern:

Be it known that I, EVERETT B. MACMIL- LAN, a citizen of the UnitedStates, residing in Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in Cars, of whichthe following corners; but in the outer set of longitudinal is aspecification.

My invention relates to cars in which the car-body is so constructedthat end platforms are dispensed with and the ends of the ears injuxtaposition act as buffers each to the other.

The object and purpose of my invention are to provide a car so builtthat in case of collision or other accident the cars will not telescopeone with the other; and I attain this object by the device shown in theaccompanying drawings, in which- Figure 1 is an elevation of the end ofthe car-frame. Fig. 2 is a plan of the floor of two cars injuxtaposition. Fig. 3 is an elevation of the ends of two cars coupled ina train. Fig. 4. is a sectional view of the framing of the car, showingthe roof-trussing. Fig. 5 is a plan view of the car, showing thecontinuous longitudinal beams. Fig. 6 is an enlarged view of the framingof the top and end of the ear. Fig. 7 is a sectional view of the end ofthe car. Fig. 8 is a sectional view of the car, showing thesuspension-rods for supporting the floor-beams. Fig. 9 is an end andsectional view of the end truss or buffer-beam of the car. Fig. 10 is aplan and sectional view of the end truss or buffer-beam of the ear. Fig.11 is a sectional view of the bufferbeam, showing the position of thelongitudinal and vertical beams. Fig. 12 is a sectional view of thebuffer-beams A, showing the top of the post B and timber 0.

Similar letters refer to similarpartsthroughout the several views.

I'Ieretofore ears for rail-ways have been made with a platform extendingbetween the two adjacent cars, which has many objectionable features. Ibuild a car that obviates the necessity of a platform in the mannerfollowing: I make the lower frame of the ear of a series of longitudinaltimbers 0, extending from end to end of the car and seated in abuffer-beam A at each end of the ear. The

exterior longitudinal timbers G are tested in a socket in the ends ofthe buffer-beam A and rest against the foot of the corner-post B of thecar, and the central longitudinal timbers O are rested in sockets in thebuffer-beam A in the center of the system of longitudinal timbers O.-The timbers G extend through the interior to the exterior plate of thebufferbeam A, being held by an angle-brace at the timbers C of thecentral system the interior and exterior plates of the buffer-beam A arebraced by angle-plates extending from the interior to the exteriorplates. The bufferbeam A is made of a piece of solid timber or theplates of metal secured together by rivets, as indicated.

On the top plate of the buffer-beam A are made the sockets D forretaining the ends of the posts B and B which are placed flush with theouter side of the buffer-beam A and support the buffer-beam A. Atie-bolt M extends vertically through the end of the lower truss-timberF, the buffer-beam A, and the bufier-beam A to secure them together. Onthe top of the posts B and B is a second buffer-beam A, and in shape itresembles the buffer-beam A. The two outside longitudi nal timbers G areheld by a suitable socket on the top of the post B and abut against theupper buffer-beam A. The central series of timbers F form thebase-timber of the rooftruss for sustaining the body of the car andgiving rigidity to the frame. The longitudinal truss is formed of thebase-timber F, supported upon the ends of the posts B B and secured bythe tie-bolt M. The longitudinal roof-truss is made of suitable materialconsisting of a longitudinal base-timber F and an upper longitudinalbeam K, having angular ends descending to and being footed in thebase-timber F and secured to the said base-timber F by mortise and thetie-bolt N. At convenient points extending between the base timber F andthe upper longitudinal beams K are placed vertical posts 0, throughwhich pass the suspension-rods J, extending down to and through thefloor-timbers C, and are secured by a nut. Between the vertical posts 0are diagonal braces H and the diagonal tie-bolt I. It will be noted thatthe braces extend in the diagonal direction, so as to brace the trussand car from the center to the ends each way.

Having thus described the parts of my invention, I now proceed toexplain the method of operating the same. The parts of the frame are puttogether, as indicated by their construction, in such manner that theupper and lower buffer-beams of the car shall be on the extreme ends ofthe car and be so related to each other that both the upper and lowerbufier-beams will resist the thrust from the car next in juxtapositionand the entire body of the car be so braced and constructed that theshock imparted to the end of a car will be transmitted through andresisted by the entire body of the car, thus effectually preventingtelescoping of the cars.

I am aware that railway-cars are not a new invention, and I thereforelay no claim to a car in the broad sense; but

WVhat I do claim, and desire to secure by Letters Patent, is-

1. In a car, the combination of an upper and lower bulfer-beam forreceiving the shock on the end of a car with a frame composed oflongitudinal timbers, and a roof-truss for sustaining the floor by asystem of vertical rods,

all substantially as and for the purpose set forth and described.

2. In a car, the combination of a roof-truss for suspending the floor ofthe car, composed of longitudinal and vertical timbers, with diagonalbraces, and the means for suspending the floor to the said roof-truss,all substantially as and for the purpose set forth.

3. In a car without platforms, the combination of a floor-frame composedof continuous longitudinal timbers held in sockets in the crossbuffer-timbers at the ends of the car with an upper series oflongitudinal timbers and sustaining-trusses, with the means forsupporting the said upper timbers, so that the impact of a blow shall betransmitted uninterruptedly throughout the entire car as a unit, allsubstantially as and for the purpose set forth and described.
